Definitions

  • the present invention relates to a device for heating a fluid.
  • the fluid is, for example, a liquid such as process water or a gas, e.g., air.
  • thermal energy from the application of electricity or from the combustion of, for example, propane, butane, or diesel fuel converted into a gaseous state and to transfer it to a liquid, such as domestic water, via a heat exchanger. It is also known that such devices can also serve as air heaters, thus heating air.
  • the stratification of the fluid must be taken into account.
  • the layers refer to the different warm components of the fluid and their resulting different densities in the container. If, for example, a warm liquid is introduced into a container from above and has a downward velocity component, several layers are usually mixed. This is also relevant for withdrawal from the container: For example, if withdrawal occurs at an upper point in the container, a warm layer cannot be completely withdrawn. If, for example, cold liquid flows in at another point during withdrawal at the upper end of the container (e.g., from a connection at the lower end of the container), and this incoming cold liquid has a vertical component, the stratification is also disturbed there.
  • containers reveal, for example, the US 2018/0051908 A1 , the US 5,054,437 A or the DE 10 2017 129 184 A1 .
  • the EP 2 476 970 B1 discloses a fluid storage device for the layered storage of at least one heat transfer fluid in a storage cavity.
  • the DE 10 2017 119 429 A1 relates to a device for the low-mixing storage and/or removal of volume flows into or from containers filled with liquid.
  • the EP 2 809 999 B1 Describes a jet atomizer arranged in front of a water inlet pipe inside a hot water tank.
  • the hot water tank has a housing with a water inlet and a water outlet.
  • the axis of a water jet flowing into the housing runs tangentially to the housing.
  • the DE 10 2006 023 067 A1 describes a hot water stratified storage tank with a container in the upper area of which there is a supply and a withdrawal line for hot water.
  • a side wall The container is connected to the ring element in a first connecting region, wherein an end face of the container is connected to the ring element in a second connecting region, and wherein the opening extends from the first connecting region to the second connecting region.
  • a longitudinal web is arranged at the first connecting region or at the second connecting region, wherein the web partially closes the opening.
  • the longitudinal opening is at least partially narrowed.
  • the web thus extends around the longitudinal side of the ring element and reduces the opening angle.
  • the web, or projection is either a separate component or an integral part of the ring element itself.
  • a deflection device which deflects the fluid in such a way that it does not mix the existing stratification in the container or that the fluid taken from the container originates from only one layer.
  • the deflection device has a ring element.
  • the fluid is thus guided in a ring and preferably only in one plane.
  • the ring element has a longitudinal opening through which the fluid can pass from the ring element into the interior of the container or from the container into the ring element.
  • the fact that it is a longitudinal opening means that the opening is located, for example, along a jacket of the ring element. It is Thus, in particular, it is not an end-face opening, as is usually the case with hoses or tubes, for example.
  • the ring element is provided with an opening laterally along at least part of its longitudinal extent.
  • the longitudinal opening is located in particular on the side of the ring element that faces a center of the ring element or a longitudinal axis of the container. The opening is therefore located on the inside of the ring element.
  • the ring element according to the invention ensures good layering even in flat containers that may not be cylindrical but, for example, cuboid-shaped.
  • One embodiment provides for the longitudinal opening to be slit-shaped.
  • the opening thus encompasses a larger angular range of the ring element.
  • the height of the slit will be addressed in the following embodiments.
  • the ring element being formed integrally with an end face of the container.
  • the ring element is, for example, part of the lid or the base of the container.
  • the front side of the container is curved towards the interior, at least in an area encompassed by the ring element.
  • the front side, on which the ring element is located is thus inclined inwards in this embodiment.
  • the curvature supports a slight mixing of the different fluid layers. If the fluid is introduced, for example, in the area of the lid, the fluid flows after leaving the ring element in the lid along the, for example, oval-shaped inside the ring element instead of flowing directly to the center of the container.
  • the front side in the enclosed area is curved away from the interior.
  • the region of the end face which is enclosed by the ring element is curved inwards, and the region of the end face which is adjacent to the outside of the ring element is flat or curved away from the interior of the container.
  • the longitudinal opening extends completely around the ring element.
  • the longitudinal opening extends only partially around the ring element.
  • the longitudinal opening extends completely over an inner side of the ring element or only over a portion of it.
  • One embodiment provides for a connecting element, for the connecting element to be arranged outside the container, and for the connecting element and the ring element to be coupled to one another in such a way that the fluid can flow between the connecting element and the ring element.
  • the fluid thus enters the ring element via the connecting element and exits the ring element.
  • the connecting element is located, in particular, outside the container.
  • the connecting element opens on the side of the ring element facing away from the longitudinal opening. This is the outer side of the ring element.
  • a complementary design is that the connecting element guides the fluid tangentially to the ring element or away from it.
  • the fluid is thus either introduced laterally into the ring element or removed from it. This depends on the application.
  • the ring element to have an oval shape.
  • the ring element has a major semi-axis and a minor semi-axis.
  • the transition between the connecting element and the ring element is located along the major semi-axis of the oval.
  • An oval as large as possible has the advantage that the velocity component perpendicular to the plane of the oval is very small. Furthermore, the kinetic energy of the fluid flow can dissipate within the oval, thus preventing unwanted turbulence with fluid from other layers.
  • the ring element has a circular shape.
  • two deflection devices are provided, each of which is assigned a common direction of rotation.
  • One of the two deflection devices is located, for example, on the lid and one on the bottom of the container.
  • the fact that both deflection devices are assigned a common - or the same - direction of rotation means that the fluid rotates in the same direction in both deflection devices - i.e., either anti-clockwise or clockwise. If the fluid is thus introduced via one deflection device and removed via the other, the same/common direction of rotation counteracts the risk of turbulence in the temperature layers.
  • the direction of rotation in the deflection devices results in particular from the position and contacting of the respective connection element.
  • One design involves the fluid being a liquid, e.g., domestic water.
  • the individual components and their connections are thus suitable for drinking water in this design.
  • the Fig. 1 shows a schematic diagram of a device for heating at least one fluid.
  • the device heats, for example, water and air.
  • FIG. 2 A container 3 is shown with two deflection devices 4, each located on the two end faces (i.e., lid and bottom). Both figures are described together.
  • Fig. 2 the line at which the container 3 for the representation of the Fig.3 is cut.
  • the container 3 has a flat design, so that the height is smaller than its length.
  • the section shows the Fig. 3 that both end faces 30 and the side walls 32 are inserted into the ring elements 41 of the two deflection devices 4
  • the container 3 and the ring elements 41 are thus realized in one piece in the illustrated embodiment.
  • the ring elements 41 are self-contained, allowing the fluid to circulate within them except for the lateral openings 42.
  • the connecting elements 40 which each merge tangentially into the ring element 41, serve as the transition between the ring elements 41 and an outer periphery (not shown here), e.g., in the form of hoses or tubes, etc.
  • the fluid is guided only in a straight line within the connecting elements 40. For example, if the fluid is introduced into the container 3 via a connecting element 40, it initially moves only linearly, then enters the ring element 41, where it is guided in an oval shape.
  • the opening 42 extends over the entire intermediate region at which the end face 30 and the side wall 32 are spaced apart from one another.
